全谱直读ICP发射光谱测定低冰镍中砷

Determination of arsenic in low grade nickel matte by ICP emission spectrograpic method

对低冰镍样品中的砷进行了试验,采用硝酸分解试样,在ICP发射光谱上测定砷元素。本法采用冶标准样品进行实验,结果与标准值基本相符,其精确度与准确度均能满足低冰镍分析的要求。

The arsenic element in low grade nickel matte samples was determined.Nitric acid was used to decompose samples,then arsenic element was detected by ICP emission spectrometry.Using national standard samples to find out the results conforming to the standard.The precision and accuracy degrees are satisfactory for the demand of geological samples analysis.
